Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are
improperly handled, results in complete or intermittent failures. Port adapters and processor modules
consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI)
shielding and connectors are integral components of the carrier. Although the metal carrier helps to
protect the board from ESD, use a preventive antistatic strap during handling.
